The “Money Monster” star will serve as an ambassador for one of the foundation’s art projects, according to ABC News, which describes Scholas Occurrentes as an organization founded by Pope Francis to bring together children from different backgrounds in hopes of increasing peace and understanding. It works in 82 countries with 400,000 schools and other institutions, the Associated Press reports.

The Clooneys weren’t the only emissaries of Hollywood at the Vatican: Actors Salma Hayek and Richard Gere were also at the event and also plan to be ambassadors in the program.

Katie Holmes' highly scrutinized relationship with Tom Cruise was made official in 2006. Six years later, Holmes filed for divorce, to much speculation that it was related to Cruise's connection to the Church of Scientology.
